摘要：

Theoretical constraints on both the polarized and unpolarized intrinsic gluon distribution functions are developed. In particular, we study the behavior of the gluon polarization asymmetry in the nucleon in the small- and large-x regions, and relate the intrinsic distribution to the retarded part of the spin-dependent bound-state potential. A simple model for the polarized and unpolarized intrinsic distributions is proposed which incorporates the QCD constraints. The model predicts that the spin carried by intrinsic gluons in the nucleon is approximately 0.5. © 1990.
